Sorry - I wrote on the assumption your Tool Collection was empty. My bad. I
think that if you Duplicate your GNU tool, you can go from there. Then you
can remove the first one on the list. When you duplicate, the new one
becomes the default, so I do not think that leaving it will cause a problem,
but, I do not know for sure. I would try it first before deleting it, just
in case you might later need/want the previous configuration???

Anyway, I hope this has helped. This has been my inaugural solution post on
the forums!
